Abstract

In this paper, a dual-rotor system model and its equation were established according to the structure and misalignment, which was transformed into equivalent bending-moment acting on out-dial. The Harmonic balance method was applying to solve equations with high-efficiency. The precision was verified by the Runge-Kutta algorithm. The misalignment resulted in fulcrum-offset, which was investigated by orbits and frequency spectrum. The results show that some new resonance region appeared when 2X frequency component plays an important role, which comes with the increase of the offset. Besides, with the increase of the offset, the rotor orbits get lager and twisted. These characteristics make help to failure diagnosis of misalignment.
